Knowledge Base: Can I resize the QR code?

You can safely scale up (increase the size of) the QR code we generate as long as you are careful to maintain the aspect ratio; that is, keep it square shaped so that the width and height are equal.

Scaling down (reducing the size of) the QR code is a little trickier. If you can do so without losing any detail, so no modules (the squares making up the code) disappear, it should still work, but the distance away from the code someone could be and still scan it will be reduced.
